Summary: Atmospheric conditions and stability effects tend to be the most
unpredictable yet most dominate forces driving the deposition, movement and
ultimate fate of the spray plume. A
series of spray trials were completed under varying atmospheric stability
conditions. Both ground deposition and
airborne concentration profiles were measured.
Meteorological data was collected using stationary meteorological stations
as well as on-board aircraft instrumentation.
The data collected in this study are used to describe spray plume
movement and deposition with changes in wind speed and atmospheric stability. The results presented in this manuscript will
provide guidance to applicators on the effect of changing weather parameters on
the fate of the spray plume.
